Instrument FrequencyCounter to use Stopwatch and StdDraw to make a plot where the x-axis is the number of calls on get() or put() and the y-axis is the total running time, with a point plotted of the cumulative time after each call. Run your program for Tale of Two Cities using SequentialSearchST and again using BinarySearchST and discuss the results. Note : Sharp jumps in the curve may be explained by caching, which is beyond the scope of this question.

You are the chief commander of US Army; you have been deployed in an ongoing war training of defusing the mine. Mines are placed on the ground which can be considered as a gird of size N*M. Each block (i, j) has a mine in it if and only if the summation of the block coordinates is divisible by 2. Your task is to move from the first row to the last row. The mines will not blow if the given rules are followed: • If you are on even row you can move to any cell that is in the neighborhood • If you are on odd row, you can only go the odd row that has mine on that and same with the unmined row. You have to develop a python program to calculate the number of ways to reach row number N starting from row number 1. Test Cases: 4 8 Output: 10

In the Mystical Garden, each flower is associated with a secret numerical code that guards its mystical properties. The code validation process involves a series of botanical calculations. The validation process is described as follows: . Calculate the product of the digits at prime positions (1-based index) from left to right. Calculate the sum of the cubed digits at non-prime positions from left to right. If the absolute difference between the results from step 1 and step 2 is a perfect square, the flower code is considered valid; otherwise, it is invalid. Example: Consider the mystical flower code 73921546. Step 1. Calculate the product of the digits at prime positions. 7*3*1*5=105 Step 2. Calculate the sum of the cubed digits at non-prime positions. 9^3 + 2^3 +4^3 +6^3=729+8+64 +216 = 1017 Step 3. If the absolute difference between the results from step 1 and step 2 is a perfect square. |105 - 1017|=912 (not a perfect square) Flower code 73921546 is invalid. Your task is to write a…

Ql: The Collatz conjecture function is defined for a positive integer m as follows. (COO1) g(m) = 3m+1 if m is odd = m/2 if m is even =1 if m=1 The repeated application of the Collatz conjecture function, as follows: g(n), g(g(n)), g(g(g(n))), ... e.g. If m=17, the sequence is 1. g(17) = 52 2. g(52) = 26 3. g(26) = 13 4. g(13) = 40 5. g(40) = 20 6. g(20) = 10 7. g(10) = 5 8. g(5) = 16 9. g(16) = 8 10. g(8) = 4 11. g(4) = 2 12. g(2) = 1 Thus if m=17, apply the function 12 times in order to reach m=1. Use Recursive Function.
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which has an index, n, as parameter and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: Fibonacci(7) is 13 Note: Use a for loop and DO NOT use recursion.
